Its visual programming environment is suited for: Developing graphics processing modules without writing a single line of codeExploring the visual technologies available in OS X without needing to learn the programming interface for that technology After installing the developer tools provided with OS X v10.5, you can find the Quartz Composer development tool in: Offset plugin for Pixelmator using Quartz Composer « Morten Nobel's Blog.
In this blog, I’ll show how to create an Offset filter for Pixelmator using Quartz Composer on Mac OS/X Snow Leopard.
Pixelmator is a really cool image editor and a great, low-price alternative to Photoshop. Pixelmater is not quite so feature rich as Photoshop and one its the missing feature is the Offset filter. Working with Quartz Composer. Sprite Kit Sprite Kit is a powerful graphics framework for 2D games such as side-scrolling shooters, puzzle games, and platformers.
A flexible API lets developers control sprite attributes such as position, size, rotation, gravity, and mass. Sprite Kit’s OpenGL-based renderer efficiently animates 2D scenes. Built-in support for physics makes animations look real, and particle systems create essential game effects such as fire, explosions, and smoke. To assist SpriteKit-based game development, Xcode supports texture atlas creation and includes a particle creator.
